Getting Started with 2D manipulations
-
I have worked almost exclusively with command line and simple GUI applications such as tracking an inventory or creating backups of a filesystem.
I have zero experience writing code that will manipulate an image and I would love at least a few pointers as to the classes I should look at first. Consider a few use cases, which is what really befuddles me.
I have an image containing a postage stamp and I want the user to interactively draw a line around around the stamp or to draw a line along the perforations.
I am simply unsure as to the base Widget or class to use to display the object so that I can then do the interaction portions. Unsure at this point if I want them to maybe just click to identify each corner (I can probably figure that out) or to click and drag to select a rectangle (that feels a bit more difficult).
I am not looking for a lot of detail at the moment, just something to play around with to make sure I am heading off into the right direction.
And now I will go see if I can write something that will simply load a single JPG and attempt to identify lines in the image (auto-identify perforations or auto-identify a stamp in an image to then make sure it is aligned in a specific way). Baby steps.

Hi,
For the GUI side, one thing you should check is the graphics view framework. This should allow you to get started.
For the auto detection part, you should check OpenCV.
